FAQ for g3 LBS
The RLS series uses g3 gas to cut GWP by over 99% while matching the arc-extinguishing and insulation strength of . This ensures eco-friendly operation at 12kV-36kV without increasing the equipment's physical footprint.
Q: What are the benefits of the integrated "Three-Position" contactor?
A: By combining ON, OFF, and EARTH functions into one system, RLS minimizes volume and features mechanical interlocking to prevent energized grounding. It is the ideal solution for compact Ring Main Units (RMUs).
Q: How does RLS ensure stability in extreme environments?
A: Featuring a hermetically sealed tank, RLS is immune to moisture and pollutants. The optimized g3 mixture prevents liquefaction at low temperatures, ensuring stable insulation and operational reliability in high-altitude or frigid regions.
